摘要
采用生物膜 膜生物反应器处理生活污水。结果表明 :在DO ,pH等因素控制得当的情况下 ,系统对COD ,NH3 -N和TN的平均去除率分别为 92 82 % ,93 0 4 %和 88 93% ,同时获得了0 15 6 gSS/ gCOD的剩余污泥产率。试验期间还对膜通量的变化情况进行了考察 。
Domestic wastewater was treated by combined biofilm-membrane bioreactor (MBR) process and the experimental results showed that the mean removal efficiencies for COD, NH_3-N and TN were 92.82%, 93.04% and 88.93% respectively when ecological factors such as DO and pH were maintained in suitable ranges. Meantime, the system obtained an excess sludge yield of 0 156 gSS/gCOD removed. Also the investigation of flux of membrane permeate was carried out and the measures for lessening membrane fouling were put forward.
